7 Claims. (Cl. 189-75) This invention relates to novel frame constructions and more particularly to novel frame constructions for windows, screens and the like, and also to certain novel frame parts. In one of its more specific aspects the invention is directed to novel combinations of demountable window and screen elements and also to novel frame and guide constructions as parts of window frames so that windows and screens may be readily and easily demountably coupled therewith. The main object of this invention is to provide a novel window and screen frame retainer and guide construction which may be readily manufactured and assembled and which is adapted to accommodate a plurality of windows or screens which may be readily and easily demountably coupled thereto. This, as well as other objects and advantages of the invention, will be readily apparent from the following description taken in conjunction with the appended drawings, wherein:

Figs. 9-11 are respectively cross sectional views taken on lines IXIX to XIX[ of Fig. 7.

As shown in Fig. 1, there may be an ordinary oblong Wooden support 10 for accommodating and carrying the elements of this invention which are composed of extruded aluminum. The oblong support 10, generally secured to the permanent walls of the home, has a cut throughout the entire inner periphery thereof to provide supporting surfaces for the aluminum elements which are secured together to provide an oblong unitary frame construction which may be easily and readily secured to the support 10.

The oblong aluminum guide and frame comprises a pair of normally vertical elements 11. Each element 11 comprises an elongated extruded dove-tail channel 12. The channel 12 has a pair of spaced outer ribs 13 and 14, with rib 14 being spaced from and materially wider than rib 13. The ribs 13 and 14 are integral with and connected to each other by connector 9 having a plurality of spaced openings 8 in the lower half length thereof. The member 11 has a plurality of inner ribs and channelways. A channelway 15 is formed by a pair of spaced and con? nected ribs 16 and 17, with the free end of rib 17 located inwardly of the free end of rib 16. These ribs 16 and 17 and integral with a narrow band 18 having an opening 19 at about the mid-length thereof for receiving a locking. pin. The rib 16 has a cut-out or slot 7 alongside of opening 19, and the rib 17 has a cut-out or slot 6 which is shorter than slot 7 and is located a short distance above slot 7. The member 11 also has an elongated central section 20 which has a dove-tail slot or channelway 21 therein. along the entire length thereof, one side of which is the rib 17. Located in the lower part of channel 21 and frictionally secured therein is a dove-tailed rib 22 having three shallow slots or cut-outs 5 therein. Rib 22 extends outside of said slot 21 a distance beyond the inside edge of rib 17 to provide a channelway 27. The rib 22 is materially less than half the length of rib 17 and extends from the lower extremity of element 11 a distance less than one-half the length of slot 21 and terminates a short distance below the opening 19. Located in said channel 12 and frictionally secured thereto is a dovetailed rib 30 extending outside of channel 12 a distance beyond rib 13 to provide a channelway 31 between rib 39 and rib 14. The rib 30 is less than half the length of channel 12 and extends from the upper extremity of element 11 a distance less than one-half the length of channel 12 and terminates a short distance above the opening 19. Each of the single extruded elements 11 also include a pair of rearwardly extending bands 35 and 36, with the ban-d 35 being integral with rib 14 and the band 36 being integral with rib 17. These bands extend the full length of said ribs and band 36 is wider than band 35 and has a plurality of screw accommodating openings through which screws 37 may pass for anchoring to a frame 10.

According to this invention, there is provided a pair of said elements 11 together with the ribs 22 and 30 and such combinations are arranged opposite each other to provide the normally vertical guides and retainers. They may be secured together in an inexpensive manner to provide a rigid and rugged frame. For this purpose, there is employed a single extruded bi-channel aluminum member consisting of an upper channel having ribs 40 and 41 con nected by cross band 43 and a lower channel having ribs 44 and 46 depending from the cross band 43. The width of the cross band 43 and the distance between the outer faces of upper ribs 40 and 41 is approximately equal to the distance between the outer faces of ribs '14 and 17; and the distance between the lower ribs 44 and 46 is approximately equal to the distance between the rib 14 and rib 13. The ribs 40 and 41 are of the same length and the ribs 44 and 46 are cut away at each end distances respectively equal to the distance between the longitudinal inner Said bi-channel member is normally the top crosspiece of the frame embodying the present invention. It is laid onto the upper extremities of the elements 11 as shown in Figs. 1, 7 and 8, with the outer edges ofcross band 43 being at the outer edges of bands 36, with the bands 36 being in approximately the same plane as the rib 40, with the bands 35 being in approximately the same plane as the rib 41, with the outer extremities of rib 46 bearing against the longitudinal edges of ribs 14 and with I the outer ends of rib 44 lying on the ribs 13. The so disposed bi-channel member is secured to the elements 11 by anchoring screws 50. An extruded aluminum channel member 51 is frictionally mounted on the ribs 40 and 41 f to provide a neat and smooth box efifect at the top of said frame.

The bottom of the frame also comprises an extruded. aluminum channel 64) whose width is approximately the same as the top bi-channel. The channel has integral therewith a narrow thin bar 61 extending upwardly from 1 its cross plate and a narrow L-shaped channel 65 integralij 3 with a rib thereof. The channel 60' is coupled with the elements 11 by disposing the ends of bar 61 in the lower ends of channel27. The channel 60 extendsacrossthe lower ends of elements .11, with. the ribs of channel 60 normally depending therefrom and being flush with the.

bands 35 and 36 and the channel 65 being disposed in the normally interior portion of the frame. The channel 60 is coupled to the normally lower ends of the elements 11 by screws 66. The ends of the cross band of the channel 60 are cut out and struck upwardly to-provide a stay or support for the lower ends of bands as. A separate extruded channel 67 of the same length as channel 60 is frictionally coupled therewith toprovide a box elfect at the bottom of the frame.

The novel frame construction before described may be easily and readily mounted in a wooden frame 10 by inserting the assembly into the cut-out therein. The assembly may be anchored thereto by a plurality of screws 37 passing through the bands 36 and into frame 10. A masking and retainer element consisting of an elongated side band 76 and a front band 77 is secured to the frame 10 by screws 78. The retaining element as shown in Pig. is disposed with the band 36 on a face of the opening and front band 77 has its free edge bearing against the full length of the frame to provide a very attractive outside appearance and a water-proof and weather-proof construction. 7

In another aspect of this invention, there are provided three separate window and screen frames 80, 81 and 82. The frame 80 comprises four extruded elements 83, 84, 85 and 86 secured to each other and carrying a pane of glass. The normally upper channel 83 has an outside slot extending along the entire length thereof and the sides thereof also have outside slots therein and are in registry with outside slots in the normally vertical elements 84 and 85 and extend the full length thereof. The normally lower element 86 has a narrow elongated channel 90 integral therewith and an outer slot therein which retains a pair of latching bolts 87 normally maintained in latching position. These bolts 87 are located at the ends of the member 86 and have fingers 89 for manually retracting said bolts 87 against the action of the springs to inoperative position. The width of frame 88 or the distance between the outer edges of the elements 84 and 85 is slightly less than the distance between the like ribs 13 and also the like ribs 22 ,of the oppositely disposed elements 11, but is greater than the distance between the like ribs 30. To demountably couple the glass carrying frame, 80 with the frame and guide structure, it may be dropped in the space below the lower extremities of the ribs 30 to rest on the inner face of the rib 14. Then by pulling the bolts 87 inwardly and moving the frame 80 upwardly it will slide on the ribs 30 which act as retainers and guides and may be moved'to its uppermost position, with the upper element 83 thereof making a snug fit in the space between the ribs 44 and 46. Then 7 the bolts 87 are released and automatically snap into a pair of the oppositely disposed openings 8 tov latch the window in its upper position. If it is desired to lower this window to some other position, it mayreadily be accomplished by retracting bolts Y87 and lowering the window and the bolts are allowedto enter either of the other oppositely disposedrpairs of openings, 8 for that purpose. If'it is desired to removethe window completely, this may be done by maintaining the bolts 87 in retracted position and lowering it beyond the lower limits of the ribs 30 when it canbe lifted out of the supporting frame. In general, in the window and frame assembly the glass carrying frame 80 is latched in its uppermost position and then another glass carrying frame '81 is also demountably coupled with the frame and guide.

The frame 81 is similar to frame, 80 except that it has a pair of short outwardly extending pins '92 anchored in its upper element and a channel 93- integral with its upper element and its lower element terminates in an apron 94 on one side. This frame 81, which also carries spring pressed bolts 95 in its lower element, is wider than frame 80. The width of frame 81 is just slightly less than the distance between the opposing like ribs 17 and the distance between the inner parts of channels 27 but is greater than the distance between like elements 13.

In order to demountably couple frame 81 to the frame and guide and even with the frame in its uppermost position, frame 81 is so placed that its pins 92 slip through the two oppositely disposed slots 6 in the ribs 17 of elements 11 and rest upon the ribs 13. The lower end of the frame 81 is tilted upwardly and its upper part is pushed up to and against the cross band 43 of the bi-channel while maintaining its bolts in retracted condition whereupon the lower end of frame 81 having passed the upper ends of ribs 22 will fall into position and the bolts 95 being released will snap into channel 21 to lock the frame 81 in its uppermost position. However, frame 81 may be lowered to various positions by merely retracting bolts 95 and lowering the frame 81 which now rides on the rib 22 located in the slots of its side members and pins 92 are still in the channel 21. It may be maintained in a number of different positions by releasing bolts 95 which enter slots 5.

The screen frame 82 may also be demountably coupled with said frame and guide. Frame 82 is similar to frame 80, differs from it-mainly in its width, and carries anchored outer pins 98 and retractable bolts 99. The width of frame 82 is greater than the width of frame 81, is slightly less than the distance between ribs 16 and greater than the distance between ribs17. For assembly purposes, the screen frame 82 is so placed that its outer pins 98 pass through the opposed openings 7 in rib 16. The frame is pushed upwardly with the bolts 99retracted and then the frame is moved into place and the bolts are released and fall into the channel 15 between ribs 16 and 17. Thus with the pins 98'and bolts 99 riding in said channel 15 the screen frame 82 may be moved to its uppermost position whereupon the released bolts 99 automatically pass into the openings 19 to lock the screen in its upper position. The bolts 99 maybe retracted and the screen moved downwardly to its lowermost position whereupon the elongated tongue of channel 65 enters into theelongated slot in the lower element thereof, to act as a stop and the bolts automatically extend beyond the lower limit of the band 18 to lock the screen frame in lowermost position.

While the invention has been described in detail, it is not to be limited to the exact construction as described because obviously many modifications and changes may be made within the spirit of this invention.
